Jason White, a dentist, said he traveled to Washington, D.C., last Friday for Donald Trump's inauguration, Fox 5 reported.

"For someone like myself that lives out here in west Texas [...] we don't really see the extreme disagreements as much," White said.

But that's exactly what he found when Monday morning, he stumbled into a Northwest D.C. coffee shop Busboys and Poets, known for their liberal, eclectic atmosphere.

Waitress Rosalynd Harris, 25, who is black, was working at the restaurant that day. She said she was still feeling energized after having participated in the Women's March on Washington the day before.

Despite their contrary backgrounds, Harris said she enjoyed chatting with White about his beliefs and politics as she served him.

"He said, 'I'm from west Texas, we don't have this. We don't have places where we can get this kind of food, this kind of atmosphere," Harris explained. "It made me happy that he could express himself in that way and be honest, like, 'I'm not from here, and I know you know I'm not from here.'"

When White left the restaurant for the airport, Harris was surprised with a $450 tip, on top of a $72.60 lunch bill.

Next to the tip was a note: "We may come from different cultures and may disagree on certain issues, but if everyone would share their smile and kindness like your beautiful smile, our country will come together as one people. Not race. Not gender. Just American. God Bless!"

"The simple fact that he didn't want to create a scene, but just wanted to let me know that this was a great experience and this is what he hopes for people in general, it was very touching,” Harris said, touched by the interaction.

The two were later reconnected via Facetime, where White explained his eyes were opened by his experience in Washington.

"I saw a lot of respect from everybody," he said. "“The American spirit was real and it was real with everybody, whether you were you a Trump supporter or were there to be a part of the Women's rally."
